Developmental analysis of locomotive behaviour during free play activities in infants.

我们研究了空间特征(行为范围、车站、机车货车等)特征与游戏能力发展的关系。本研究的目的是观察7名1~4岁婴幼儿在陌生环境中的运动行为。记录方法是超声波运动定位仪(Takei&Company，Ltd.)和录像机。结果如下。1)机车车距、里程、速度等机车行为量化指标随年龄增长而增加。2)在机车范围内有多个车站(基地)。3)最具特色的车站在母亲周围。4)其他人在玩具盒、家具和其他成年人周围。机车货车有两种，一种是经过几个车站的圆形机车货车，另一种是从一个车站到另一个车站的圆形机车货车。6)运动行为通过加入兄弟姐妹来促进，否则会被不熟悉的婴儿所抑制。

We studies the relationships between characters of spatials(ranges of behavior,functions of station,locomotive truck and so forth) and developments of playing ability. Purpose of this study is the locomoyive behavior by 7 infants from aged 1 to 4 years in an unfamiliar situation. Methods for recording are ultra sonic locomotion locator (TAKEI & Company,Ltd) and VTR.The results are as follows. 1) Quantitative indication of locomotive behavior such as distance of locomotive truck, range and speed are increasing according to age of years. 2) There are several stations (bases) in the locomotive range.3) The most dintinguished station is around mother. 4) Others are around toy box,furniture and other adults. 5) There are two types of locomotive trucks,circular type in which they have traveled several stations and a round in which they traveled from one station to another. 6) Locomotive behaviors are facilitated by joining siblings, otherwise inhibited by unfamiliar infants.
